WEIGHT-OPERATED CIRCUIT-CLOSER.

Specification of Letters Patent. Patented Sept. 14, 1920.

To all whom it may concern Be it known that 1, CHARLES H. MCNEIL,

' for supporting a-nursing bottle so that the same is conveniently held with respect to the infant, and consequently the constant attendance of the nurse or mother during the feeding operation will not be necessitated.

It is a further object of the invention to produce a bottle holding device wherein the bottle is yieldably supported and which is provided with means for sounding an alarm when the contents of the bottle are used, so that the same may be refilled and alsoso that the infant can not suck in air from the on the line 44'of Fig. 1.

Fig. 5 is a side elevation. parts being in section and illustrating .a modification.

Fig.6 is an enlarged detail vertical sectional view of the milk bottle suspending device, the rod, yoke and slidable block being in elevation.

While in the accompanying drawings I have illustrated my improvement in connection with a baby carriage, it is to be understood that the same is not to be thus restricted in itsuseful application, as the de vice may be attached to the crib of an infant.

On the horizontal stile 10 of one side of a baby carriage I secure upper and lower plates 11 and 12 respectively. The upper plate is in the nature of the shade rod support for the carriage, a portion of the shade rod which is attached thereto being indicated by the numeral 13. The plates 11 and 12 are connected by screws 14, and consequently are removable. The upper plate 11 has a threaded opening therethrough, as may likewise the lower plate. The stile 10 is provided with an opening registering with the referred to openings, and if desired this last mentioned opening may be also threaded. Engaging in the threaded openings is the threaded end 15 of a vertically disposed rod 16. This rod has arranged thereon, outward of its threaded portion 15 an offset or laterally extending element 17 which is in the nature of a handle, so that the said rod may be easily and quickly screwed on the support 10, or as quickly removed therefrom should occasion so require.

Arranged for slidable movement on the rod 16 is a block 18. Passing through a threaded opening in one side of the block and contacting with the rod 16 is a thumb screw 19 which holds the block 18 adjusted on the rod "16. The block 18 has secured thereon a longitudinally disposed rod 20, and the outer end of this rod is threaded. The horizontal rod 20 is not only susceptible to vertical adjustment with respect to the supporting rod 16, but the same may be turned to desired angles on the said supporting rod and clamped by the thumb screw 19. The outer endof the rod 16 has a hexagon brass nut 21 threaded thereon to prevent the block 18 from slipping off of the rod 20 in case the block 18 should get loose. Y

On the rod 20 is a slidable block 22 having a threaded opening from the outer end thereof receiving a thumb screw 23 that contacts with the rod 20 and holds the block 22 adjustable on said Tod. Swiveled to the under face of the block 22 by a headed element 2 1 is a yoke 25. Received in this yoke, and supported thereby is a ring 26. The ring 26 is provided with an opening that is surround by a boss 27. The boss has a threaded bore in which is received the threaded end of a tube 28.

Passing through the tube 28 is a rod 29 that also passes through the opening in the ring. The rod 29 is the suspending element for the milk bottle and has its outer end formed with a hook 30. The hook is held against turning movement by being disposed beneath the arms provided in the bifurcated end of a plate 31, the latter being integrally formed on a cap nut 2 which engages therewith and which closes the lower endof the 7 tube 28. Restingon the cap nut is a hel cal spring 33 that is, of course, arranged in the thereof intothe ring 26.! The hook 30 is 'de signed to engage with the ring 35 on a cage tube, and this spring contacts with stud or lug 34; on the rod 29 whereby to normally force the rod upwardly and one of thefeiids 36 which supports the milk or feeding bottle '37, and by the arrangement .as-above' deto the crib or carriage and at any desired elevation tosuit the convenience of the infant.

7 Bridging the ring 26 is a band 38 of elec- J tr1c conductlng materlal. The sides of time band are spaced away from each other by a block of insulating material which is indi- "cated by the numeral 39. To one side of theband is soldered or otherwise secured one end of. an, electric conductor 40, and

connected to an adjustable element 41 that passes through a threaded opening in the block 39 is a second electric conductor 22.

The element 41 is inthe nature of ascrew--.

which passes a binding element in the nature and is therefore, of course, adjustable. The

end of the screw is arranged opposite the upper end of the 'rod29, and by adjusting the screw so that the same contacts with the said I rod the pressure of the spring 33 between the cap nut 32 and the'stud' or lug 34- may be likewise adjusted. In this manner difierent V quantities of milk may be arranged in the 7 bottle 37 sufficient, however, to hold therod 29. out of contacting engagement with the I V adjustable conductor 41.. Thering 26 as well as the rod 29 are of electric conducting material, and the conducting wires 40 and 42 are wrapped together. in the usual, manner and v are suspended-upon the bottle supportingdevice by elastic bands 43. These wires connectwith'a plug 44 to which is attacheda. switch 45 the said switch engaging with the plug 461-having conductor wires 47 and 48,

which lead to a source-or" electric energy 49 that 1s 1n circult-wltha buzzer 50.

vAs stated, the weight of the milk the j members, forming one contact, mounted on bottle is designed to keep the conducting rod 29 out of engagement with the contact 41. As the baby consumes the milk the spring 33 through the contact and through the ring 26,

thus completing the circuit through the buz- I zer 50 The sound of. the buzzer will attract attention tothe nurse so that the bottle may berenioved and refilled if necessary, and

conse uently the infant will not be permitted 2 to sue in air from the bottle so that danger of an attack of colic, common 1n such 1nstances will be obviated.
